I love Maple because of the
Robert Frost poem, I wouldn't use it because it doesn't fit my criteria for a name.
Kate's ok, but kinda dull. I think you can pull it off as a full name but obviously some people might assume it's a nn. Oddly enough, I know a bunch of
Catherine or
Katherine who all go by their full name. I know one Polish
Katarzyna who lives in the UK and goes by
Kate.
